Configuration
The Configuration section of serial port information includes the electrical interface (Port
Type) and basic serial settings.
Signals
In the Signals section shows the serial port signals are green when asserted (on) and gray
when not asserted (off). The meanings of the signals are:
RTS
Request To Send.
CTS
Clear To Send.
DTR
Data Terminal Ready.
DSR
Data Set Ready.
DCD
Data Carrier Detected.
OFC
Output Flow Control. This signal indicates that flow control is enabled on the remote
side of the serial-port connection, and that the Digi device should stop sending data.
IFC
Input Flow Control. This signal indicates that the Digi device is operating as if flow
control is enabled for incoming data sent from the remote side of the serial-port
connection. This signal is more of an indication that flow control is intended or expected
rather than true state information. If the remote side has a flow-control mechanism
enabled, the Digi device will use it.
